Researchers also found out that alteration in usual sleeping habit disallows body to maintain sugar levels.
In the trial of three weeks, an environment is created for the subjects so that they constantly feel jet lagged. This environment focused on regulation of diets, activities, hours of sleep and sleep disruptions.
At the end of three weeks, 21 subjects identified with increased sugar levels were found out to be pre-diabetic. Over the years, several studies have also implied that shift workers are more likely to develop obesity or diabetes. This study has thrown light upon the mechanism of how it happens.
Dr. Orfeu Buxton of Harvard Medical School headed the research panel. He explained, “What we found in this study was that when we induced circadian disruption (activity and rhythm disruption) in the laboratory for three weeks we could alter glucose metabolism in a way that would predict elevated diabetes risk. It suggests that the mechanism by which night workers have increased diabetes risk is an insufficient release of insulin by the pancreas.”
However, researchers were unsure of no response of pancreas. Dr. Buxton stated that subjects were provided with identical meals when they rested, although pancreas did not respond to identical meal in order to secrete sufficient insulin for holding glucose levels in the normal range.
“Shift workers who stay awake at night are much more likely to progress to full-on diabetes than day workers. Since night workers often have a hard time sleeping during the day, they can face both circadian disruptions due to working at night and insufficient sleep during the day.”, added Buxton.
Therefore, here is evidence on sleep’s significance for health, and sleep should be at night for its best effect.
